TMS9000-2 OPERATOR MANUAL OPERATING PROCEDURES
Published 02-21-2019, Control # 611-05
Engine
Warm-up Procedures for All Temperature Ranges:
1. Upon startup, allow the engine to idle for 3 to 5 minutes
before operating with a load.
2. Cold Engine Startup: After allowing the engine to warm
by idling it for 3 to 5 minutes, slowly increase the engine
speed to provide adequate lubrication to the bearings
and to allow the oil pressure to stabilize.
Transmission
Operating the transmission with a sump temperature below
normal operating temperature is limited to:
• operating in the neutral gear or
• driving with an unloaded crane while not exceeding
1500 engine RPM and not exceeding half throttle.
Warm-up Procedures for Rough Terrain (RT) and
Industrial Cranes:
1. Engage the parking brake and apply the service brake.
2. Shift the transmission into the highest gear and increase
the engine RPM to 1500 for 15 seconds, then allow the
engine RPM to return to idle.
3. Repeat Step 2 until the temperature of the transmission
sump reaches normal operating temperature.
Alternate Warm-up Procedures for Rough Terrain (RT)
and Industrial Cranes:
1. Setup the crane on outriggers.
2. Engage the transmission with 4-wheel drive selected (if
equipped) and allow crane to run at idle until the
temperature of the transmission sump reaches normal
operating temperature.
NOTE: Warm-up operation of 4-wheel drive transmission
engaged in 2-wheel drive only could cause
transmission damage.
Alternate Warm-up Procedures for Truck Mount (TM/
TMS) Cranes:
1. Setup the crane on outriggers.
2. Engage the transmission and allow crane to run at idle
until the temperature of the transmission sump reaches
normal operating temperature.
Hoist
Performing a warm-up procedure is recommended at every
startup and is required at ambient temperatures below 4°C
(40°F).
Warm-up Procedures:
1. Without operating the hoist function, warm the hydraulic
oil (see the following section).
2. Once the hydraulic system is warm, operate the
unloaded hoist, in both directions, at low speeds several
times to prime all hydraulic lines with warm hydraulic oil
and to circulate gear lubricant through the planetary
gear sets.
Swing Drive and Turntable Bearing
Warm-up Procedures for Temperatures Above -7°C
(20°F):
1. Setup the crane on fully extended outriggers, with the
boom fully retracted and near maximum lift angle with no
load applied.
2. Rotate the superstructure at a speed of less than one
RPM for at least one complete revolution in one
direction, then rotate the superstructure at a speed of
less than one RPM for at least one complete revolution
in the opposite direction.
Warm-up Procedures for Temperatures Below -7°C
(20°F):
1. Ensure the boom is fully retracted and near maximum lift
angle with no load applied.
2. Rotate the superstructure at a speed of less than one-
half RPM for at least two complete revolutions in one
direction, then rotate the superstructure at a speed of
less than one-half RPM for at least two complete
revolutions in the opposite direction.
Axles
Warm-up Procedures for Temperatures Below -35°C
(-30°F):
1. Setup the crane on outriggers.
2. Engage the transmission and allow crane to run at idle
until the temperature of the transmission sump reaches
normal operating temperature.
Hydraulic Oil System
Operating Limits and Warm-up Procedures:
• From 4°C to -10°C (40°F to 15°F): Crane operation
without
a load is allowed with medium engine RPM and
medium function speed (joystick position) until the fluid
reaches at least 10°C (50°F). It is then recommended
that all crane functions be cycled to remove cold fluid
from all components and cylinders of the hydraulic
system. If there is any unusual sound coming from the
crane’s hydraulic pumps or motors, stop the operation
and engine immediately and contact a Manitowoc
distributor.
